摘　　要：目的:观察实时超声反馈对腹横肌运动控制的影响,探讨下背痛患者腹横肌运动控制训练的方法。方法:对33例试验对象随机分组,比较在有无实时超声反馈下两组试验对象腹横肌的收缩率,腰椎稳定性从1级上升至2级所需的训练次数和训练时间是否存在差异。结果:腹横肌收缩率(P=0.662>0.05)两组间无差异;训练次数(P=0.018<0.05)和训练时间(P=0.011<0.05)两组间存在差异,且训练次数均值试验组(1.5次)小于对照组(3.1次),训练时间均值试验组(13.4min)小于对照组(30.8min)。结论:实时超声反馈不会增加腹横肌收缩的效率;实时超声反馈能使试验对象用较少的次数,在较短时间内掌握腹横肌收缩的方法。Objective： To observe the effect of real-ultrasound feedback on the motor control of transversus abdominal muscle （TrA）; To explore the way for patients with low back pain to retraining the motor control of TrA. Method： Thirty-three subjects were allocated at random to the experimental group and the control group. The experimental group performed the way to contract TrA with real-ultrasound feedback, while the control group performed that alone. Result： ①Non significant difference was found in TrA contraction-ratio between the groups （P=0.662 〉 0.05）; ②Significant differences were found in training times （P=0.018 〈 0.05） and training time （P=0.011 〈0.05） and the means of both training times （1.5〈3.1 times） and training time （13.4〈30.8 min） in control group were less than that of experimental group. Conclusion： The real-ultrasound feedback does not increase the TrA contraction-ratio, however it contributes to make it easy for subiects to master the way to contract TrA.
